查来查去都是什么乱说一通，改这地方改那地方，我了个去的，太不靠谱了，后来综合各个老外的说法，思考了下然后试着去改，老天真照顾我，好用了。哈哈～～～

首先查到的是Capybara不在rspec中，所以要添加进去，但是添加的是spec_helper.rb文件中

config.include Capybara::DSL

结果：依然没解决。

其次，因为版本升级，现在rspec已经分为两块，一个spec_helper.rb和一个rails_helper.rb
从生成的测试文件看

require 'rails_helper'

RSpec.describe "StaticPages", :type => :request do
# describe "GET /static_pages" do
#   it "works! (now write some real specs)" do
#     get static_pages_index_path
#     expect(response.status).to be(200)
#   end
# end

describe "Home page" do
it "should have the content 'Sample App'" do
visit '/static_pages/home'
expect(page).to have_content('Sample App')
end
end
end

引用的是rails_helper，所以我试着把这个东西移到rails_helper中，问题解决。

其他小问题一大堆。。。头疼，下班。
